I've just posted phpFlickr version 1.4.2. This release fixes several bugs for Windows users (thanks to Allan Larsen). I'm also happy to mention that Flickr has released their photo deletion API call to the public. You can now use the photos_delete(photoid) function to delete a photo. Obviously, you should do this with care because once you do this, your photo is gone. Also, you should only let apps that you completely trust to ask for "delete" privileges. It'd be a trifling matter to delete all of your photos without asking you nicely. It's not that I expect that behavior from the Flickr API developer community…I'm just saying.
